Tony Ford - Extreme Ab Routine
You took this straight from p90x.
Even the phrase at the end:Do not do this routine every day. You do not work other parts of your body every day.
Tony Horton says "Do not do this everyday. You don't work other parts of your body and you shouldn't do abs, especially ab ripper x. lets all go into child's pose."
I know because I purchased P90X and it has changed my life.
